WINDOW FASTENER.

Application filed October 4, 1926.

The invention relates to improvements in window fasteners and an-object of the inventionis to provide a device which canbe readily attached to an existing window and which will-permit of the easy adjustment of the sashes inthe frameandwhich will effect the positive fastening ofthe sashes in their closed positions and which when 'properlyadjusted will "hold either of the sashes in selected open positions.

A further object is to construct the device so that the lower sashcan beopened a predetermined amount for ventilating purposes and positively fastened in that position against movement in any direction.

A further'objectof the invention is to provide releasable means for fastening the upper sash closed during the interval that the lower sash is being adjusted.

A further object of the invention to construct the appliance in a simple, durable and. inexpensive manner and such that it can be readily attached to the existing window.

With theabove more important objects in view, the invention consists essentially in the arrangement and constructionof parts here inafter more particularly described, reference being had to the accompanying drawing, in which Y Fig. 1 is an interior view of a portion of window showing mywinvention applied thereon. Y

My device is adapted for use :on unbalanced sashes and comprises the parts now described. An upper substantially L-shaped bracket 8 is permanently secured'suchas by screws to the upper end of one of the inner battens and a further bearing-bracket 9 issecured to the said batten in a locationadjacent the upperend of the lowersash. The brackets vertically aligned and support rotata- 'bly a vertically disposed circular rod 10, the

upper end of which is swivelly mounted in the horizontal arm of the upper bracket and the lower end of which is-rotatably-mounted 1n the bearing of the bracket '9 and has the extremity thereof turned at right angles to provide a handle 11.

To one of the uppercorners of the lower sash, I secure a spring casing 12 which is formed from a substantially metallic str ip bent to provide an open ended box 13 and having the ends thereof lapped and fastened by screws 11 i and 15 to the sash. The box-13 receivesthe rod and theside walls of the box are provided with opposing vertical slots '16 and 17 which receive side lugs 18 and 19 providedon a flat spring 20 placed within the box it being understood that the lugs are placed in the slots prior to the box being-secured to the sash. The springis bowed in'a direction away from the rod and has the opf posite ends thereof forming upper and lower spring catches 21 and 22 which ride the {face I of the rod.

The rod is provided throughout its length and at one side with a series ofsimilar suitably spaced notches 23 which notches are in the path of travel of the spring 20 when the handle 11 is parallel to the side of the wiI dow frame or in the position as shown in Figure The notches are made such that when the rod is fin such latter position and thelower sash is raised,*the upper spring prevents the sash from dropping.

When it is desired to close the lower sash or re-adjust it in a downward direction, one swings the handle 11 to the position shown inFigure 1 and in so doing causes the notch in which the catch is caught to move away from the catch with the result that both catches are free to travel up or down the engaged surface of the rod.

It is desirable to fasten the lower sash in its closed position and I have provided a further notch 24 in the rod adjoining the lower end which notch is adapted to receive the catch 21 and by engagement therewith prevent the said sash from rising, the handle 11 at this time being parallel with the sash. When it is desired to open the lower sash, it is unlocked by swinging the handle 11, 90 degrees or from the position shown in Figure l to that shown in Figure 2. The rotary movement of 'the rod so produced passes the catch 21 out of the notch 24 and so releases the sash and at the same time passes the series of notches 23 into the path of travel of the subsequently up moving catches which travel with the sash as it is being opened.

It is also desirable, such in the winter time, to have the lower sash open a small amount and fastened against movement in either direction. This accomplished by providing a latch 25 pivotally attached to the casing 12 by the screw and present ing a catch 26 adapted to enter a cross slot 27 provided in the lower part of the rod. The latch can be readily manipulated by the fingers and it can only be entered in the notch when the handle 11 is in the position shown in Figure 2.

The upper sash 2 is fitted also with a box like spring casing 28 permanently fastened to one of the upper corners thereof by screws 29 and 30. The said casing receives the rod and it contains a spring catch 31 fastened by a rivet 32 to the said casing. The spring catch 31 is adapted to ride the face of the rod and to enter the notches 23 when the rod is turned to the position shown in Figure 2 and the said sash is moved. It will be observed that the spring catch 31 extends downwardly with the result that it is free to escape out of the notches in the up movement of the sash 2 and serves to hold the sash against down movement by contact with the right angled shoulder of the notch, it being understood that the handle of the rod is at such time parallel with the side of the window frame. According to the above, it will be seen that the catches 22 and 31 engaging the notches 23 serve to fasten the sashes in open positions.

As the turning of the handle 11, however, inwardly to a position parallel with the lower sash, would simultaneously pass both the latter catches out of the notches, it is desirable to provide means for holding the upper sash closed before turning the handle. Such a device is accordingly provided and comprises a pivoted catch 33 carried centrally by the upper cross bar of the upper sash and engageable with a stationary catch sash is closed.

34 secured to the lintel of the window frame. The catch 33 is supplied with a hand grip 35 extending normally away from the sash in the position best shownin Figure 7 and held in such position by suitable springs 36 provided.

When the upper sash is in the open posi tion, the springs 36 hold the catch 33 in against the sash and when the said sash approaches the closed position, the catch 33 engages with the catch 34, initially moves out and then springs in and becomes caught in the position shown in Figure 7 and accordingly holds the upper sash closed. operator can readily release the upper sash by grasping the handle and pushing it towards the sash.

Usually one either opens the bottom sash or the upper sash. If the'bottom sash be closed, one can release the catch of the upper sash and then fasten the upper sash in any desired open position by means of the catch 31 and the notches 23 and at this time, he does not require to bother about the lower sash when turning the rod as-such Whilst I have entered into a detailed de- I scription of the structural arrangement of the catches, it will be readily understood that I do not desire to be limited to the structure shown as such could be readily struc- The On the other hand, if the turally modified without departing from the spirit of the invention as set forth in the appended claims. What I claim as my invention is 2- 1. The combination with a window frame and upper and lower sashes mounted for vertical sliding movement within the frame,

of a vertically disposed rod rotatably car-I ried by the frame and havingthe lower end thereof provided with a handle "for rotating the rod and the body of the rod provided throughout its length and at one side with a series of suitably spaced notches presenting each a right angled shoulder and a sloping face there above, spring casings permanently secured to the sashes and receiving the rod and spring catches mounted in the casings and riding continuously the rod, said catches being adapted to enter the notches in the raising of the sashes and fasten the sashes in various adjusted open positions and said notches being designed to release the catches in the turning of the rod under the manipulation of the handle.
